POSITION HOLDING CONTROL FOR A TRANSPORT PROCESS

The present disclosure relates to a control apparatus for a delivery system, comprising: a control module configured to control a power converter coupled to a motor; and a modification module. The modification module is configured to: estimate a dimensional parameter of an item conveyed by the motor; determining whether a hold command is received; and if a hold command is received, modifying one or more parameters of the control module based on the estimated dimensional parameter of the item to hold the rotor of the motor at a rotor hold position. 本公开涉及一种用于输送系统的控制装置，包括：控制模块，该控制模块被配置为控制耦接到马达的电源转换器；以及修改模块。该修改模块被配置为：估计由该马达输送的物品的尺寸参数；确定是否接收到保持命令；并且如果接收到保持命令，则基于该物品的所估计的尺寸参数来修改该控制模块的一个或多个参数，从而将该马达的转子保持在转子保持位置处。
